Chatter & Ping!!!!

[polishing_frenchman]

There's nothing more rewarding than when we make such simple changes to our cars and achieve great results,thankyou dear forum,oh thankyou!!!
After some evening reading i decided to make some changes to S2 Avant intake/airbox.
Changed my stock air filter (well overdue) for an ITG foam panel type £36,drilled three 1" holes in cold side of airbox below filter line, drilled another two 1" holes below trumpet,removed all 'plastic crap' as Rusty would say from behind headlamp and fitted a Forge DV from big Lee £40 .
The change in how the car pulls,well,im still trying to get my head around,and the noise i now have the chatter when i let off and an awesome pinging sound on boost not chavy whatsoever, just music to my ears.

Umm...pinging (or pinking) = predetonation = engine damage is heading your way.

This.

Maybe someone should have bought an Impreza.

I wouldn't dare modify my air filter panel in any way..unless I knew what I was doing which I don't so I'll leave everything alone

I didn't mention it but, in my opinion, opening up the airbox and letting warm/hot air be drawn from inside the engine bay is a step backward performance-wise from the factory's cold air intake plumbing.

I fitted a 4" port on mine rather than cutting it up

/\ This is the best way to do it IMHO

wait til the summer comes and it'll be drawing tons of pre-heated air and it will be sluggish unfortunately. When you go back to a more stock like approach it will feel amazing BTDT.
